Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to an exhaust treatment device and a waste incineration facility for incineration of general waste or industrial waste, and the like. Treatment method [Advanced technology] Dioxins that contain toxic substances in addition to dust or acidic and harmful gases in the exhaust gas discharged from waste incineration facilities. In order to decompose and remove the dioxins, various measures are taken. Figure Series 5 is a schematic diagram showing the structure of waste incineration facilities of the prior art. As shown in Figure 5, series a combustion furnace * is connected to boiler c via a gas mixing chamber b located on the outlet side of combustion furnace a, and the exhaust temperature is reduced to 600 to 700. The middle part of the boiler c is provided with a high-temperature dust collector d. A reaction tower f equipped with a sprayer e on the top and a screw conveyor g on the bottom are connected to the exhaust side of the boiler c. The bag filter h, the treatment gas is discharged from the chimney j to the atmosphere through the induction fan i. On the other hand, on the discharge side of the screw conveyor g, a chute pipe k, a conveying conveyor m, and a bucket elevater η are connected to capture the vibrations from the bag filter h. The ash is conveyed to the chute P provided on the upper part of the combustion furnace a through the sliding pipes k, the conveying conveyor m, and the bucket elevator η. The processing steps of the exhaust gas and fly ash constituting such an incineration facility are described below. Fly ash and acidic and harmful gases composed of incombustibles and uncombustibles generated in the combustion furnace a and about 80 ° ° (: containing dioxin, etc.) are exhaust gases of this paper standard applicable to Chinese National Standards (CNS) A4 specification (210 X 297 mm) L --- 1 --- I ---------- ^ --------- 1 j-{Please read the precautions on the back before (Fill in this page) Printed by A7 _B7 of the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. 5. Description of the Invention (2) After the unburned material is reburned in the gas mixing room b, it is introduced into the boiler c to cool it down. The high-temperature dust collector d in the high temperature range above ° C removes the fly ash contained. At the same time, the micro-organic vapors adsorbed on the fly ash are mostly thermally decomposed before generating dioxin *. They are once treated. The above-mentioned exhaust system is introduced into the reaction tower f 'and elixirs such as slaked lime slurry sprayed from the sprayer e are used to neutralize the acidic and harmful gases contained in it. In addition, the bag filter h in the next step will be in Fly ash, organic chloride, and neutralization reaction products and unreacted elixir, which have not been removed by the temperature collector, are filtered and removed. The exhaust gas will become clean gas, which will be attracted by the inducing fan i and discharged from the chimney j into the atmosphere. "After the above-mentioned trapped ash system captured by the bag filter h is properly vibrated, it will slide through the screw conveyor g. Tube k, conveying conveyor m, and bucket elevator η are put into the combustion furnace a from the chute p, and are heated to decompose organic chloride or neutralize the reaction in the gas-hip mixing chamber b at about 80 ° C. And unreacted medicament, and the residual trapped ash is discharged from the recovery ports q and r located at the bottom of the combustion furnace a and the boiler c. [Problems to be solved by the invention] However, the waste incineration facilities of the prior art described above are The calcium content of the harmful gas neutralizer sprayed by the reaction tower f and recovered in the bag filter h is discharged out of the facility from the recovery ports q and r, so it is not reused, not only can not save the use of expensive drugs At the same time, because it contains heavy metals or dioxins and other harmful substances, the capture ash needs to be highly harmless (this paper size applies the Chinese National Standard (CNS) A4 specification (210x297 mm) _ 5 _ L ---- -------- ^ Install -------- Order -------- -Line S.-(Please read the notes on the back before filling in this page) Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 ______B7_ V.

Also, in the high tropical zone above 800 ° C, quick lime C a 0 is generated due to the thermal decomposition of the reaction product Ca C 1 2 and the unreacted agent Ca (〇H) 2. However, it is a short time Residual C a 0 that cannot be completely combined with gas elements in the exhaust gas in solid-gas contact will be directly discharged, so 'reaction with surrounding or moisture in the air will cause heat to be dangerous, and' in the recombustion chamber b ' The organic gaseous substance that was almost completely thermally decomposed was subsequently synthesized from the reaction tower f to the bag filter h to become dioxins. Therefore, the problem that the capture of the bag filter h is incomplete occurs * Another On the one hand, in addition to the above-mentioned advanced technology, the activated carbon adsorption method for dioxin removal is generally performed. • The activated carbon that adsorbs dioxin is discharged directly to the outside. Therefore, the amount of ash discharged will be increased, and the post-treatment costs will be increased. The problem occurred. [Means for solving the problem] The exhaust treatment equipment of the waste incineration facility in the scope of patent application No. 1 of the present invention is a waste incineration facility for incineration of general waste or industrial waste, etc., and is discharged from the waste incinerator. After the exhaust gas is introduced into the recombustion chamber for recombustion, the exhaust gas is introduced into the bag filter from the recombustion chamber through a cooling means such as a gas cooling device or a waste heat utilization device, and is constituted by a harmful gas neutralizing agent and Dioxin-type carbon-based adsorbent is used to remove dust and acidic harmful gases contained in exhaust gas and dioxin-type paper standards are applicable to China National Standard (CNS) A4 specifications (210x297 mm) — 〇 " I ---- -------- 'ί Install -------- Order --------- Line ν.' · _-(Please read the precautions on the back before filling this page) A7 B7 V. Description of the invention (4) Exhaust gas treatment equipment, characterized by being equipped with an ash-collecting circulation device that can capture the ash shaken off by the above-mentioned bag filter and can be introduced into the above-mentioned reburning chamber, meanwhile, it is stacked on the above-mentioned reburn The reburning ash at the bottom of the chamber can also be introduced into the above bag filter. Reburning ash treatment device on the side * The exhaust gas treatment method of the waste incineration facility according to item 2 of the patent application of the present invention is to introduce the radon gas discharged from the waste incinerator into the reburning chamber for reburning, and then reburn The chamber introduces the exhaust gas into the bag filter through cooling means such as a gas cooling device or a waste heat utilization device. The harmful gas supplied to the bag filter is used to neutralize the dust and acidic harmful gases contained in the exhaust gas with a liniment and a carbon-based adsorbent. Exhaust treatment method for hip and dioxin waste incineration facilities * Its special features are: before the filtration operation is started, the harmful gas neutralizing agent and carbon-based adsorbent are introduced at the inlet side of the above-mentioned bag filter, and the surface of the filter cloth of the bag filter A pre-coat layer is formed, and the dioxin is adsorbed by the carbon-based adsorbent, and the captured ash containing the carbon-based adsorbent shaken off by the bag filter is introduced into the recombustion chamber *.
